WASHINGTON: After weeks of pain for US consumers at the gas pump and the grocery store, the worst appears to be over. Oil prices have fallen, with gas soon to follow. Demand for farm commodities, like the corn used in everything from cereal to soda, has dropped. And businesses remain slow to pass along higher costs because customers aren't getting raises and might walk away. Inflation isn't much of a worry for economists these days. “I think the bulk of the big price increases are over,” said Gus Faucher, an economist at Moody's Analytics. Lower prices – or at least a break in their steady rise – will come as a big relief. Consumer prices rose 3.2 percent for the year ending in April, the most since October 2008. Higher food and gas prices drove the gains. Excluding those two categories, prices rose 0.2 percent in April. They rose 1.3 percent over the past year, below what the Federal Reserve considers healthy. Economists study this figure, known as core inflation, because food and energy prices are volatile. Some inflation can be healthy for the economy because it encourages people to spend money and invest rather than sitting on their cash. More spending drives corporate growth, which makes businesses more likely to hire people. Inflation was a much bigger concern in March. Oil prices were rising steadily because of the unrest in the Middle East. Some feared gas could reach $5 a gallon, leaving Americans much less money to spend on cars, appliances and vacations. That kind of drop in spending would squeeze corporate profits, delay hiring _ maybe even tip the economy back into recession. But last week, oil prices sank by the most in two and half years. Americans drive less when gas prices get high enough, and concerns about slowing energy demand sent oil prices tumbling – from $114 at the start of May to about $97 on Friday. Now the nationwide average for gas nationwide has leveled off. On Friday it was just under $4 a gallon ($1 a liter), where it's been for the past week. Many analysts say it could drop to $3.50 as soon as next month. he prices of milk, bread and chicken won't fall as fast – it could take six months or longer, analysts say – but they could decline by the end of the year. That's because the price of corn and other grains have fallen. Overseas ranchers are using less corn for feed, and US farmers have planted more.
